Gapuwiyak, also known as Lake Evella, is an Aboriginal Australian community located in north-eastern Arnhem Land, Northern Territory, 25 kilometres (16 mi) south of the head of Buckingham Bay and about the same distance south-west of Arnhem Bay.

[citation needed] In the 1960s David Burrumarra advocated for the creation of the community as a part of the outstation movement.

[3] The community is serviced by a barge from Darwin once a week that comes up the Buckingham River.

[citation needed] The community comprises Aboriginal people from many different families or clans.

[citation needed] In April 2017, a four-day festival to mark the Rom ceremony was attended by about 500 people at Gapuwiyak School.
